LEN -MOUNTING FOR EYEGLASSES.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed July 10, 1905. Serial No. 269,093.

To all whom it may concern:

Be it known that I, JOHN R. VAN TASSEL, of Geneva, in the county of Ontario, in the State of New York, have invented new and useful Improvements in Lens-Mountings for Eyeknown as the post, or portion between the box and lens, is disposed at an angle with the mechanical axis of said lens. The object of this angular neck and lateral offset of the box is twofold, first, to permit the mounting to be inverted, so as to throw the lens up or down to different positions without changing the angle of the lens or its mechanical axis-that is, the position of the lens may be changed vertically with reference to the eyeand, second, to permit the model to be reversed for the purpose of throwing the lens nearer to or farther from the eyethat is, in one case the lens may be shifted vertically with reference to the eye and in the other case horizontal at different distances from the eye.

Other objects and uses will appear in the following description.

In the drawings, Figure 1 is a front face view of a pair of rimless eyeglasses and my improved mounting therefor. Fig. 2 is an enlarged face view of a portion of a lens and the adjacent mounting, including a portion of the nose-guard and bow. Figs. 3 and 4 are sectional views taken on line 3 4, Fig. 2, showing the mounting in the reversed positions for supporting the lens at different disor piece of metal, as seen in Fig. 5, which is folded upon itself, so that the ends of the strip are parallel and are spaced apart the distance equal to the thickness of the lens and constitute the ears 1, which are clamped to opposite faces of the lens by a suitable clamping-screw 4, the intermediate portion of said strip being bent into the form of a loop open at both ends and constituting the box 2, while the intervening portions of the opposite arms of the strip between the box and adjacent edge of the lens are-brought into close contact with each other to form the comparatively thin neck 3.

The head or box 2 is substantially rectangular in cross-section and is offset at one side of the neck 3, so that it lies in a plane at one side of the lens a, the object of which is to permit the lens to be supported at different distances from the eye by simply reversing the mounting from the position seen in F ig. 3, for instance, to the position seen in Fig. 4:.

One of the arms of the folded strip of metal which constitutes the mounting is offset laterally at 5 a distance substantially equal to the thickness of the lens, and this offset portion 5 is provided with opposite prongs 6, constituting. lens-guards, which engage the periphery of the lens some distance above and beneath the ears 1. These lens-guards are usually slightly tempered, so as to retain their shape and to insure a more perfect contact throughout their lengths with the adjacent edge of the lens, and it will be clearly apparent that by making these lens-guards and other parts of the mounting from a single piece of metal there is no necessity for soldering any of the joints, and therefore the usual weakening of the lens-guards by the drawing of the temper, due to the heat necessary in flected upwardly in full lines and downwardly by dotted lines, such change being made by simply detaching the screws 4 and 8 and turning the mounting upside down and then resecuring the lens to the mounting without changing the angle of the lens. Both of the mountings are made by the same die or dies, and they are therefore identical, but reversely arranged when the lenses are mounted therein. It therefore follows that these mountings are interchangeable, so that when one is reversed and it is desired to keep the lenses at the same distance from the eyes it may be placed upon the opposite lens and the one on that lens changed over to the other lens. It is now clearly apparent that the lenses may both be brought to the same height or to different heightsthat is, they may both be lowered when the mountings are in one position or brought to a more elevated position when the mountings are inverted. This is perhaps better explained by stating that the necks 3 may be inclined downwardly, as seen in Fig. 1, or upwardly, as seen in Fig. 2, or, if necessary, one may be inclined downwardly and the other upwardly for holding the lenses with their mechanical axes at different heights. Again, the mountings may be placed so that the lenses stand in substantially the same plane at one side of the boxes 2, as seen in Fig. 3, or both may be reversed, so as to bring the boxes at the opposite side of the lens-plane, or, if desired, one may be arranged so as to bring the lens close to one eye and the other to cause the lens to stand out farther from the other eye. This form of mounting, therefore, provides for a wide range of adjustment without bending or in any way refitting the mountings.

The boxes 2 are adapted to receive the adjacent ends of the bow b and nose-guards c in addition to a U-shaped washer 7, and the opposite sides of the box, together with the inclosed ends of the bow 6 and nose-guards c and also the washer 7, are provided with alined apertures for receiving a clamping-screw 8. The aperture in the side of the box 2 adjacent to the head of the screw 8 is sufiiciently large to permit said head to pass therethrough and engage the adjacent side of the washer 7. In this instance the adjacent ends of the bow b and nose-guard 0 are interposed between the opposite sides or arms of the washer 7, so that when the threaded part of the screw 8 is engaged with the side of the box nearest the lens and the head of the screw is engaged with the opposite arm of the washer 7 the ends of the how 6 and nose-guard c are firmly impinged between the opposite sides of the washer.

What I claim is 1. Aone-piece lens-mounting consisting of a strip of metal folded upon itself forming an open loop or box and ears, the opposite arms being brought together at one edge of the lens between the ears and box for forming a comparatively thin neck, said box being offset beyond the plane of the lens, and also disposed in a horizontal plane above the ears.

- 2. Aone-piece lens-mountingfor eyeglasses consisting of a strip of metal folded upon itself, its intermediate portion forming a box which is disposed at one side of both the horizontal and vertical planes of the ends of the strip.

3. A lens-mounting for eyeglasses comprising lens-clamping ears, a box and a comparatively thin neck connecting the ears to the box, said neck being disposed at an angle with the ears, and the box being offset to one side of the neck.

4. A one-piece lens-mounting for eyeglasses consisting of a strip of metal folded upon itself, its intermediate portion forming an open loop or box and its ends being disposed in parallel planes spaced apart to receive the lens, one of the opposite arms being offset toward the other to bring portions of the two arms together forming a comparatively thin neck between the box and lens, said neck being inclined at an angle with the mechanical axis of the lens, and the box being offset and disposed in a plane at one side of the lens.

5. A one-piece mounting for an eyeglass, said mounting consisting of a strip of metal folded upon itself, the intermediate portion being deflected vertically at an angle with the ends and forming an open box which is disposed in a vertical plane at one side of the ends of the mounting.

6. In combination with a lens, a strip of metal folded upon itself and having its ends secured to the opposite faces of the lens, one of the opposite arms being offset laterally across the edge of the lens and provided with a projection engaging the edge of the lens, the intermediate portion of said strip forming an open loop located at one side of the vertical plane of the lens for the purpose described.

7. Alens-mounting for eyeglasses comprising an ear secured to the lens and ofiset laterally across the edge of the lens, said offset having oppositely projecting lens guards bearing upon the edge of the lens, a box united to the ear in combination with a bow and noseguard secured within said box.

8. A lens-mount for eyeglasses comprising an ear secured to the lens in line with its mechanical axis, a box rigidly connected to the ear and located in a plane at one side of the mechanical axis and also disposed in a plane at one side of the vertical plane of the lens.

9. A one-piece lens-mounting for eyeglasses consisting of a strip of metal folded upon itself, its central portion forming a loop or box and the ends spaced apart to receive the lens, the portions between the ends and box being brought into juxtaposition to form a comparatively thin neck, said neck being deflected vertically at an angle with the ends and the box being ofiset horizontally beyond the plane of said ends for the purpose described. 10. A lens-mounting consisting of a strip of metal having its intermediate portion bent into the form of a loop or box and its ends separated forming ears to receive the lens, the portions of the strip between the box and ears being brought together to form a comparatively thin neck, and means to secure the ears to the lens.

11. A lens-mounting having a box open at both ends, a bow and a nose-guard each having one end inserted into the box and a U-shaped washer also inserted in the box and receiving one of said ends, one side of the washer being interposed between one side of the box and the adjacent end of one of the other parts inserted in said box and a clamping-screw having a head engaged with one side of the washer and having its threaded end. engaged with the threaded aperture in the opposite side of the box. 7

12. In a lens-mounting, the combination with a lens, a one-piece strip of metal having its ends secured to opposite faces of the lens and its intermediate portion forming a box, and a bow and nose-guard each having one end secured in'the box.

13. In combination with a lens, a one-piece strip of metal having its ends secured to opposite faces of the lens and its intermediate portion forming a rectangular box, and a noseguard having one end inserted in the box, and means to secure said end in the box.

14. In combination with a lens, a one-piece strip of metal having its ends secured to opposite faces of the lens and its intermediate portion forming a rectangular box, one-of the ends of said strip having oppositely-projecting spurs forming lens-guards engaging the edge of the lens.

In Witness whereof I have hereunto set my hand this 29th day of May, 1905.
